Answer:
a = 7
Step-by-step explanation:
3(1 - 2a) = -3a - 18
3 - 6a = - 3a - 18
Add 18 to each side:
3 + 18 - 6a = - 3a - 18 + 18
21 - 6a = - 3a
Add 6a to each side:
21 - 6a + 6a = - 3a + 6a
21 = 3a
3a = 21
Divide each side by 3:
3a ÷ 3 = 21 ÷ 3
a = 7

Answer:
The ratio of juices to ginger ale is 2 to 2
The ratio of orange juice to the cranberry juice is 1 to 1

Charlotte and Riley walked 6/10 of a mile to school one day, and then after school they walked 3/8 of a mile to the store. From the store back home was another 2/5 of a mile. How far did the girls walk in all?
Answer: The girls walked [tex]1\dfrac38[/tex] miles.
Step-by-step explanation:
Given: Distance from home to school = [tex]\dfrac{6}{10}[/tex] mile
Distance from school to store = [tex]\dfrac38[/tex] mile
Distance from store to home = [tex]\dfrac25[/tex] miles
Total distance = [tex]\dfrac6{10}+\dfrac38+\dfrac25[/tex]
= [tex]\dfrac{6\times4+3\times5+2\times8}{40}[/tex] [L.C.M.(10,8,5)=40]
= [tex]\dfrac{24+15+16}{40}[/tex]
= [tex]\dfrac{55}{40}[/tex]
= [tex]\dfrac{11}{8}=1\dfrac38[/tex] miles
Hence, The girls walked [tex]1\dfrac38[/tex] miles.

Find the value of x. 120
Answer:
x = 25
Step-by-step explanation:
2x + 70 = 120 {Subtract 70 from both sides}

2x = 50 {divide both sides by 2}
x = 50/2
x = 25
